Celebrity sites are abuzz over a report that Whitney Houston's February death in a hotel bathtub was a murder orchestrated by "high-powered drug dealers who sent thugs to collect a huge debt she owed."

Take it with a grain of salt as the report comes from the National Enquirer, which spoke with a top private investigator in Hollywood. Paul Huebl says he has the evidence — the killers were caught on video, he claims — and he's turning all of his materials over to the FBI, who so far have been quiet on the report.

Huebl says he re-examined the coroner's report and disagreed with an assessment that no foul play was involved, pointing to defensive wounds that indicated Houston "was battling for her life" before she died at age 48. The PI also used a network of drug informants to gather evidence he's giving to the FBI field office in Chicago, hoping for a new look at the case.

The detective says the killers blended in with Houston's group of hangers-on at the Beverly Hills Hilton and video captured them slipping into her room. The motive? Huebl says Houston's drug debt had reached $1.5 million — she received a cocaine delivery the day before — and that she complained of being harassed to cough up the cash.

Huebl argues she ended up paying with her life instead.

Kevin Federline's brother: Britney Spears' 7-year-old is my son

Did Britney Spears cheat on Kevin Federline with his brother? In
court papers, Christopher Federline says not only did Spears sleep with
him, there's evidence of their affair: her son Sean Preston, now 7,
according to RadarOnline.com.

The revelations come in documents
for a temporary restraining order that Christopher Federline filed Dec.
18 against Spears in Florida, claiming the singer-turned-"X Factor"
judge stole his credit card, blackmailed and harassed him. To sum it up:
"She is out of control and a maniac," he said in the documents.

Christopher
Federline says she lifted his card from his wallet while picking up her
kids at his brother's house, then ran up $4,500 in charges. When he
confronted her, he claims, she mocked him and made disparaging remarks
about his genitalia.

“She also blackmailed me and told me if I
tell the police that she stole my credit card, that she will tell the
world I’m the true father of Sean Preston, not Kevin," he said. "I do
confess I slept with Britney, and I am the true father, but the public
does not need to know."

Too late for that now.
